Extreme-scale computer architecture: Energy efficiency from the ground up

Josep Torrellas
2014 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2014  
To construct such a chip, we need to rethink the whole compute stack from the ground up for energy efficiency -and attain Extreme-Scale Computing.  ...  Moreover, we also need techniques to reduce the leakage of on-chip memories and to lower the voltage guardbands of logic.  ...  Minimizing Energy in the On-Chip Network The on-chip interconnection network in a large chip is another significant source of energy consumption.  ...
